T76

After pressure washing a T76, have a parasitic draw of 400 milliamps on the 25 amp drive controller fuse. Unplugged the drive controller box harness, still have draw. Any suggestions.

The cab connector is underneath the cab, raise the cab (if you have stick machine you have to remove the handles inside the cab by the 4 bolts, if you have joystick you have to do nothing), secure the cab with the shock lock and disconnect the battery, after that, glook on the RH corner, if you stand in front of the machine on the LH side, Behind, the shock on that side, is a grey big connector, disconnect that and blow it carefully out with shop air. Don't blow to hard so that the seal is not flying away.
After that you have to go in the belly of the machine, next to the pumps, same side, look for a Blue Controller (might be behind a black rubber cover), carefully disconnect the connector (do not use any type of tool on these) and also carefully blow these out. Be careful with the orange seal!
After you blew out these connectors and let them dry a little bit, connect them again and connect the battery back. Now the machine should function normal again.

How old is your machine? What year was it purchased?

While you have the connectors apart, I like to dab some dielectric grease on the contact points to keep corrosion at bay ...

Do NOT do that! We had only problems with that! Even Bobcat told us not to do that, instead use the dialectical grease on the seals from the connectors, BUT never on the Pins!

That's odd, as I have been using it on the pins for decades to keep corrosion away. Will have to look into it.....

Hey Fortworth-cowboy. Thanks for the direction. Looked into using dielectric grease on connector pins and you were right-on. I've been doing wrong for ages and appreciate someone pointing it out to me.

It's not what you know, but what you know that ain't so.

You're very welcome!
